T 00% whom it may concern:

Be it known that I, RALPH J. SHIPLEY, a citizen of the United States, residing at VVaterbury, in the county of New Haven and State of Connecticut, have invented new and useful Improvements in the Process of Making Paper-Fasteners, of which the following is a specification.

My invention has for its object an improved method of making the dupleX-pronged metallic fasteners known as McGills Fasteneners, and the consequent production of such fasteners free from burr-surfaces with unvarying exactness in the irregularity of the length of the shanks of each fastener and the close and set parallel contact of all the folded parts of the fastener, and the doing of this in a' simple, practical, rapid, economical, uniform, and automatic manner.

The improved method is hereinafter set forth in the claims, reference being made to the accompanying drawings, which exhibit a machine suitable for holding, receiving, and bending the metallic blanks into the desire g5 form.

In the drawings, Figure 1 represents an elevation of the machine. Fig. 2 is a plan view of the same. nal sectional view taken on the line a: so, Figs. 1 and 2. Fig. t is an elevation of the receiver or sheath forholdin g the blanks. Figs. 5 and 6 are detail views, in larger size, of the pin and secondary head. Figs. 7, 8,9, 10, and 11 are detail views showing the various stages of bending the blank.

In the drawings, the letter A indicates the main base-frame of the machine, and A its upright portion.

The shaft B for driving the mechanism is journaled in bearings upon the upright frame A, and said shaft carries the fly-wheel E, driving-clutch D, cams O C, and crank-wheel Q. The "clutch D is connected and disconnected by the clutch-lever D Abelt driven 45 by suitable .power is used upon the pulley of the clutch D to operate the machine. The

connecting-rod R extends from the crankwheel Q to a sliding headPin guide-slides O O in the frame A to move the headup and down. Upon the face of the sliding head P is an anvil P, and this anvil is shown as rest- Fig. 3 is a vertical longitudi-' ing upon a bracket which is part of the sliding head, and said anvil is held to the head P by a set-screw 4, and is adjustable verti callyby the set-screw P Upon the upper end of the, sliding head P is a bracket-arm S, and passing vertically through said bracketarm is a screw T, that is attached at its lower end to the secondary head U, which is free to slide in guides inthe frame A, and the jam-nuts Onsuch screw connect it by and to the bracket S and cause the head U to be moved in unison with the sliding head P. Upon the back of the secondary head U is a socket V, one side of which is slotted. (See Figs. -5 and 6.) WVithin the socket V is a pin-holder W, and the pin X passes through thisholder W and through the heads U' and P, and the frame A is slotted at a for this pin X. The screw Y passes through the holder \V and clamps the pin X in place; but said pin may be removed or fed forward as worn.

There is a pin 5 secured to the holder W, and said pin passes through the slot in socket V and through the fork or slot of the lever Z, and there is a nut 6 and washer 7 connecting the holder W and lever Z, the said pin 5 being free to move up and down in the forked or slotted end of the lever Z as the head P and secondary head U are raised and lowered. This lever Z Z is pivoted at A to a lug of the frame A, and the end of this lever has a roller or friction-wheel Z, which is acted on by the cam O, which imparts to said lever and the pin X a forward motion,the retractile spring B imparting the return movement.

,There is a bracketed table F secured to the frame A at its upper part, and upon the said table is the slotted dovetailed block G, into which is received the dovetailed end block h of the blank-holding sheath H, which is 'filled with superimposed metal blanks with the burr-surface of each and every blank facing in the same direction. The sheath H is affixed in the slotted dovetailed block G by its dovetailed end block h, and in such position delivers by gravity to the block G all the fastener-blanks contained therein with their burr-surfaces facing down.

The interior shape of the sheath or case H IOC corresponds with the shape of the fastenerblanks, as does the interior of the slotted block G, to which the case H is affixed. The case H is filled with metal blanks for making paper-fasteners, superimposed therein with the burr-surfaces of each and every blank facing in the same direction. This may be done by hand, but is preferably and automatically accomplished by afiixing the case beneath the punching-dies of a machine for punching paper fastener blanks such as shown and described in my patent,No. 382,911, of May 15, 1888, filed jointly with the application of which this is a division.

The sheath or case H is slotted to its hollow center on one side from its dovetailed end block h clear through its other end, and is provided with a spring block or support g, movable lengthwise in said slot, upon which the blanks lie as they are fed downinto the sheath, and this support is pressed down by the blanks as they accumulate. When the sheath is filled, it is reversed and aflixed by means of its dovetailed end block it in the slotted block G of the machine proper. The spring block or support g is released and helps by its weight to increase the gravity of the descent of the fastener-blanks through the case into the slotted block G and down on the table F. it increased gravity is required, it is obtained by securing a weight to the ring in the head of the set-screw g in the-spring-block 9.

An arm, hg Fig. 1', is employed to. clamp and hold the sheath H in the block G. The forward endof the table F is made with guideways ff,

in which works the slide-block I, and to the block I is connected the feed-blade J. This blade J is moved back and forth above the table F and below the block G and between the. end guidesf f, and said blade pushes or takesthe bottom blank from the pile of blanks in the slotted block G and delivers it to the bending mechanisms with the surface of the blank facing the same as it did in the slotted. block-to wit, downward. These end guides f f are set so that the distance from the center or diameter of the pinX to one of them is greater than that to the other, to enable the feedrblade J- to deliver the fastener-blank under the pin, X in such position that theblank may be folded out of center, or so that oneof its arms or shanks will be longer than the other,for an object hereinafter described.

The slide-block I has an arm 1, connecting it to the rod K and carriage K, and there is-a lever IL, whose slottedupper end is connected by a pin to the carriage K, and said lever L ispivoted at A to a lug upon the frame A, andv the end of the lever L carries a frictionroller. M, which is acted upon by a cam. 0 upon the driving-shaft B to impart to the carriage K rod. K, arm I, and pushing-blade J a forwardmovement, a spring N retracting the lever L to deliver the blanks.

There are sliding stocks D vD in the frame A, and connected to them are the jaws E E,

which, with the stocks, can be moved horizontally. The spring-arms F F are connected at their lower ends by bolts 8 to the sides of the upright frame A, and the upper ends of said springs bear against the outer ends of the stocks D D and act to press them and the jaws E toward each other, and tend to keep the jaws closed, but allow them to be pressed apart.

Upon a pivot at 10 is the bent lever g g, and connected to it and to the frame A is the helical spring 11'. The upper end of this bent lever is slotted, and connected to it by the pivot-pin 7b is the clearer G. This clearer G passes through one bracket of the table F,

and its bent end projects ,over the anvil P.

This clearer and bent lever are operated by the slide-head P, the foot-piece of g passing under the lower side of said slide-head P, so that the descent of the. slide-head moves the clearer G forward, while its ascent allows the spring H to, force the lever backward and move the clearer out of the, way.

The operation of the machine in forminga paper-fastener from the blank is as follows:

The metal blanks a from the sheath II and slotted block G are pushed or removed one at a time and delivered by the feed-blade J between the end guides, f f upon the up.- per edge of the jaws E E and beneath the pin X with their burr-surfaces. facing downward, as in the. slotted block G. The descent of the. slide-head 1? brings down the projecting pin X, as, seen in Fig. 7, and saidpin, pressing the blank at a. point a little to one side of its, center, bends it i'ntoa shape, as

shown in Fig. 8, with one of its members or sides of the V longer than the other,and the bnrredsurface of theblank consequently facing outward. The further movement of the pin X as it acts on the rounding corner of the jaws opensthein and bends theblank as seen in Fig. 9, and the pin and bent blank descend between the jaws, and as the pin-.X passes belowthe jaws they close. upon the blank, bending, it around the pin, and, bringing its arms together,.hold it, in. place, as seen inFigs. 1 and; 10. The further movement of the mechanism, now withdraws the pin X, leaving the'blank held by the jaws E, and

the slide-head P is raised. and the anvil connected. thereto is brought to bear upon; the open round head of tlieblank andflattens the same into the form shown in Fig. 11, ,and at the same time the pin X has been raised with the heads. and is projected by the lever 7 Z, r

and by this time another metal blank has been pushed upon the upper edges of the jaws E by the feed-blade J and-thepartsare again-in the position shown. in Fig. 7,, ,ready by the descent of the pin X to. form another fastener, which operation opens thejawsE and releases the firstmade fastener, so. that it isfree to fallintoa receptacle provided for the purpose. In casethe fastenersso formed Should not fall away when released, but should stick upon the anvil P, the clearer G,

moving across the face of the anvil, acts to remove the fastener and cause it to fall into the receptacle provided for that purpose.

To produce the Me Gill dupleX-pronged fastener invariably free from-all burr-surfaces,

with one of the fastener-shanks invariably and regularly longer than the other to facilitate their. after separation, and the finished fastener with all its folded parts invariably in close-set parallel contact, was almost impracticable under the method of manufacture heretofore practiced, and could only be accomplished, and then indifferently uniform, by 1a great expenditure of time, labor, and ski Itwill be observed that according to my improved method the fastener-blanks are superposed in the holding sheath or case H with their burred surfaces all facing in the same direction, and that the case H thus filled is affixed in the slotted block G in a manner to deliver the blanks to it in similar position, and that consequently each fastener-blank is successively pushed from the base of the superimposed column of blanks below the base of the block G and automatically fed to the bending mechanism in similar position-that is, with its burr-surface facing downwardso that the forcing of the blank down between the clamping-jaws E E by the descension of the pin X, as seen in Fig. 9, helps to rub the burr from the duplex shanks, While the rising of the heading-anvil P, and its consequent swag-ing or pressingthe open round head of the blank into form against the under side of the jaws E E, as shown in Fig. 11, accom-' plishes the same end for the part of the blank forming the fastener-head; that all the burr that remains is on the outside surface of the fastener thus formed, and consequently may afterward be readily and cheaply removed by the tumbling process. Further, that according to my improved method of manufacture the fastener-blank being carried by the guideways f f out of center under the pin X, the pin X consequently folds the blank out of center and forms the round open head therein, as shown in Fig. 10, with one arm of the folded blank longer than the other, and that the rising of the anvil P then flattens, swages, and sets this head in manner to securely hold the arms in such position-that is, differing in lengthto facilitate their after separation I when put in use. Further, that, according to my improved method the fastener-blank being first formed with its shanks of the correct varying lengths and in close parallel contact, with the center of the blank forming a round open head, and the shanks being securely held in this position by the clamping-jaws E E, while the round open head is closed and swaged flat by being pressed between the.

a face of the anvil P and the under surface of the jaws E E, this pressure on the outside surface of the head from below and above tends to swage, draw, or spread the metal on the outside surface of the head, and thereby set the fastener with all its folded parts in close parallel contact, and to form and set each and every fastener uniformly and invariably alike, Without any tendency of the folds to spring apart when the fastener is released from the forming-machine.
